Additional Performance Enhancement

The following are some of the latest creations designed to

enhance the security, quality and efficiency of the radios.

ASTRO 25 Enhanced Data

ASTRO 25 Enhanced Data is optimized to handle different

message sizes and update rates from different applications.

Install Enhanced Data to the Integrated Data system with a

software installation to improve data channel efficiency and

enable denser network traffic.

Dynamic System Resilience (DSR)

DSR seamlessly switches the radio system to a backup master

site during system failures. DSR also provides additional

indication e.g. failure detection, fault recovery, and redundancy

within the system to address to the user in need. Mechanisms

related to the Integrated Voice and Data (IV & D) or data centric

are all supported by DSR.

CrossTalk Prevention

This feature prevents crosstalk scenarios from happening,

especially when a wideband antenna is used. This feature

allows the adjustment of the Trident Transmitting SSI clock rate

in the radio to be different from the Receiving Frequency. This

subsequently reduces the possibilities of radio frequency

interfering spurs and it also prevents crosstalk.

Encrypted Integrated Data (EID)

EID provides security encryption and authentication of IV & D

data bearer service communication between the radio and the

Customer Enterprise Network.

SecureNet

SecureNet allows user to perform secured communications on

an Analog or Motorola Data Communication (MDC) channel.

The MDC OTAR feature will allow users to perform OTAR

activities on an MDC channel.

Example Description

Home button

Buttons and keys are shown in bold print

or as an icon.

Phone

Menu entries are shown similar to the
